Visit the Landsat Collection 2 Surface Reflectance webpage for additional information and documentation. The LEDAPS and LaSRC surface reflectance algorithms correct for the temporally, spatially and spectrally varying scattering and absorbing effects of atmospheric gases, aerosols, and water vapor, which is necessary to reliably characterize the Earth’s land surface.Ĭollection 2 Surface Reflectance Enhancements Surface reflectance (unitless) measures the fraction of incoming solar radiation that is reflected from the Earth's surface to the Landsat sensor. Landsat 4-9 surface temperature products are generated using the Landsat surface temperature algorithm ( Version 1.3.0), developed in cooperation with the Rochester Institute of Technology and NASA Jet Propulsion Laboratory. Landsat 4-5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper (ETM+) surface reflectance products are generated using the Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) algorithm ( Version 3.4.0). Landsat 8/9 Operational Land Imager (OLI) surface reflectance products are generated using the Land Surface Reflectance Code (LaSRC) algorithm ( Version 1.5.0). Landsat Level-2 science products are generated from Collection 2 Level-1 inputs that meet the <76 degrees Solar Zenith Angle constraint and include the required auxiliary data inputs to generate a scientifically viable product. This internationally-recognized certification recognizes satellite data that have been processed to a minimum set of requirements and organized into a structure that allows for immediate analysis with minimum user effort and interoperability both through time and with other datasets.
